HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 493,996, dated March21, 1893.

Application filed October 3. 1892.

, To all whom it may concern:

Be it known that I, LAWRENCE FRANKLIN GRESSETT, a citizen of the UnitedStates, residing at Ballinger, in the county of Runnels and State ofTexas, have invented a new and useful Hay-Press, of which the followingisa specification.

My invention relates to improvements in presses for baling hay, &c., andthe objects in view are to provide a cheaply-constructed, durable,easily-operated, and powerful press adapted to conveniently andcompactly bale the hay.

Various otherobjects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings: Figure 1 is a perspective View of a pressembodying my invention. Fig. 2 is a longitudinal vertical section of thesame. Fig. 3 is a plan. Fig. 4 is a transverse section through the rearend of the press. Fig. 5 is a detail in perspective of the spring detentin the upper side of the press. Fig. 6 is a similar view of the detentsemployed at the sides of the press.

Like numerals of reference indicate like parts in all the figures of thedrawings.

The bed of the press comprises a pair of opposite longitudinalside-sills 1, connected at intervals by suitable tie-bars which supportthe floor of the press. Blocks 2 are securely bolted intermediate theside-sills, and embrace the rear end of a forwardly-extending beam 3.The beam 3 has let therein a series of three transverse beams 4, and thesame are connected by opposite longitudinal beams 5, thus forming, ashort distance in advance of the baling-charnber, a power-supportingplatform to be hereinafter described. Vertical standards 6 rise from thebeams 1, and are securely bolted, that is the front standards, with aseries of longitudinal side-strips 7. The central strips 7 of the seriesare unbolted or disconnected from the rear standards, but are borne uponby opposite pairs of cranked adjusting-screws 8, that are passed throughthreaded perforations formed in the rear standards. By means of theseset-screws the side-walls of the press, at their rear ends, may becompressed, or the exit of the press decreased in size as is common andfor the well- Serial No. 447,632. (No model.)

known purpose. oted in the side walls in advance of the front pair ofstandards, and springs 10 are secured to the side-walls and have theirrear ends engaged under, and bearing upon, the tails or front ends ofthe detents, whereby their rear ends are spring-pressed into the press.

The standards extend above the side walls and support the rear roofll ofthe press,and said roof is provided,-at.its front end, with a pair ofopenings through which project the arms 12 of a transverse detent 13.These arms are borne upon by the free front ends of a pair of fiatsprings 14, that are secured to the upper side of the roof.

At opposite sides, and at the rear corner, of the power-supportingframe, previously de-' scribed, a pair of standards 15 are mounted,whose inner edges are recessed and have journaled therein, uponvertical'axles, guide-rollers 16, whose adjacent faces are spaced apart.Between these guide-rollers there is mounted for reciprocation theplunger 17, which is provided at its inner or rear end with the usualplunger-head 18. The plunger is further supported and guided by means ofa pair of metal straps 19, rising from the beam 3, and above and belowthe plunger is journaled a pair of friction-rollers 20.

Upon acasting mounted on the power-supporting frame there is located avertical axle 21, and eccentrically mounted upon the axle and adapted torevolve is a disk or wheel 22, whose periphery is provided with a tireor flange 23, that extends above the upper side of the wheel. The outerend of the plunger is bifurcated, at24, and has journaled within thisbifurcation a loose roller 25, adapted to ride over the aforesaid tireofthe power-wheel 22. A link 26 is pivotally connected with the axle 27of the said roller 25, embraces the edge of the tire of theeccentrically-mounted power-wheel, and within the same is provided witha small guide-roller 28, that is designed to ride around the inner edgeor periphery of the wheel. At intervals, brackets 29 are -mounted on thepower-supporting frame and arranged in a circle, and in each bracket ananti-friction-roller 30 is located. This completes the construction ofthe press, with the exception of the draft-pole 31, which is mountedupon the disk or wheel and secured by L-shaped detents 9 are pivclips32. The roof of the press is slightly shorter than the remainderthereof, so that an opening is formed at the front of the press throughwhich the material to be baled may be passed.

In operation, the press is operated by horsepower, in this instance, butmay be operated by other means if desired, but in either instance thepower-wheel is revolved, and being eccentrically mounted and connectedwith the plunger, draws the same in and out of the press at eachrevolution of the wheel, said wheel being balanced and partly supportedduring its revolutions by means of the small anti-friction rollers 30.At each outward reciprocation of the plunger the material to be baled isfed into the opening in rear of the plunger, and is squeezed orcompressed by the plunger-head against the usual head-block. It will beobvious that by the construction of press thus described I am enabled toproduce a cheap and simple press, that is strong and durable andpowerful in its operation.

It is to be understood that changes in the form, proportion and theminor details of construction may be resorted to without departing fromthe principle or sacrificing any of the advantages of this invention.

Having described my in vention, what I claim is- 1. In a press,thecombination with the baling chamber, the power platform, and the stubshaft, of the eccentrically mounted grooveless power wheel 22, providedon its periphery with a tire 23 that extends above the upper side of theWheel forming a peripheral flange, the friction rollers mounted on theplatform at intervals and supporting the power wheel, the plunger 17,having its front end bifurcated and provided with a roller 25, to rideover the outer face of the tire of the power Wheel, a link 26 pivoted tothe end of the plunger by the same bolt that forms the journal for theroller 25, and the roller 28 journaled on the end of the link andengaging the inner surface of the tire, and resting on the plain upperface of the power wheel, substantially as described.

2. In a press, the combination with the baling-chamber, the beam 3projecting therefrom, the transverse beams mounted thereon, the castingmounted on the beams and provided with a vertical axle, the disk havingthe peripheral flange mounted eccentrically on the axle, the draft-polemounted on the disk, the anti-friction rollers located in the path ofthe disk, the plunger mounted in the baling-chamher and bifurcated atits front end, a shaft passed therethrough, a wheel mounted on the shaftwithin the bifurcation, a loose connection between the end of theplunger and flange of the power-wheel, a loose roller on the linkengaging the periphery of the power-wheel, standards at opposite sidesof the plunger, guide-wheels journaled therein and embracing theplunger, metal straps secured to the main beam and embracing theplunger, and pulleys or rollers journaled in the straps above and belowthe plunger, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two witnesses.

LAWRENCE FRANKLIN GRESSETT.
